While l have shown and described cylinder 1 as being provided with three sets segmental deflecting-Wells, the shape and nun1- her of the latter of course may be changed Without do erting from the spirit or scope of the eppen ed claims, and I reserve the right to make such other changes fell within the scope of said When a roasting or crying upper constructed with my iniproven'ier' sion is made for simple; 'ug two cntly lnounted and two indeoe driven cylinders so arranged each other that the through the primary cylinder therefrom is received directly t ond cylinder, and at the some is med-e for preventing the esce the heated gases or products of at the adjacent ends without 1 the cylinders shall he fitted ti 'l' other and Without requiring the supplemental strm'zture to encompass hilt ed jecent ends.

Serious trouble and inconvenient, it turns we-cyiinders are fitted t such way to have a i it expansion end contrec end to the unevenness o; exp-er r traction oi the pests the end o (not nozzle et at this misses contraction at the end of the ct er. when l isni'is constructed in such Way as to my improvements, the cylinders can be thus brought close together or even overa rotary kiln, two communicating ene suitably mounted one of which is ed with furnace, end, ehlest arranged communicating ends of the cylinders necking the heme from the furnace at int between the said communicating in a rotary kiln, two communicating cylinders independently mounted and arin axial alinement, one cylinder being larger in diameter than the other to receive the discherge end of the latter, a furnace coinper son with the err tension end.

. lsppedtha.t is, have the end of one nserted into the end or the other-without the neity of a tight oint, for I provide means connnuniceting with one end of the large cylinder, and an annular nozzle communicating With the opposite end of said large cylinder and a blast.

3. In a rotary kiln, two communicating cylinders suitably mounted one of which is provided with a furnace, an annular nozzle arranged at the communicating ends of the cylinders, and en annular casing with which the nozzle communicates.

i. In a rotary kiln, a cylinder rotatably mounted, deflecting-Walls suitehly arranged in said cylinder, and en porting-Wells suitebly arranged in said cy nder, and supportlDg'C0lUHiDS interposed between the deiicctl f 1 *l' (1 mg i ens and the it ui 0 ti so; in er.

7 e kiln or furnace two cylinders in n inent independently mounted and indetly driven, one having its delivery end to the receiving end of the other end ider arranged relatively to the arranged to deliver material directly from the first to the second, and each being out of contact with the other, and rneai'is for preventing the esoa )6 of air or I roiluets of eombustion at the piece Where t eir ends are ad.- jaeent, substantially as set forth.

8. In a rotary kiln, a rotary cylinder having a furnace at or eomn'iunicating With. one end thereof and having at the other a central or axial discharge for the products of (50111 bustion from the said furnace, and means for delivering streams or a eurrent of air or equivalent agents at the interior peripheral part of said cylinder at the end opposite to the furnace to prevent or eheeli the escape of prorluets of combustion from said peripheral part, substantially as set forth.

9. In a rotary hiln, rotating eonimunieat ing cylinders, one h swing its end-insr-irtecl into the other Without contacting therewith and means for preventing the escape of air or products of combustion at the piece Where vthey overlap, substantially as set forth.

In testimony whereof I afl'ix my signature in the presence of two witnesses.
